    Areas affected...Parts of southern LA...southern MS...and far
    southwestern AL

    Concerning...Tornado Watch 6...

    Valid 150443Z - 150645Z

    The severe weather threat for Tornado Watch 6 continues.

    SUMMARY...A heightened tornado risk is evident over parts of
    southern Louisiana into southwestern Mississippi in the near term --
    within Tornado Watch #6. A downstream tornado watch will be issued
    within an hour.

    DISCUSSION...A squall line with embedded mesovorticies and supercell
    structures is tracking eastward across southern LA and southwestern
    MS tonight. The line is impinging on a corridor of middle/upper 60s
    dewpoints, which is yielding weakly unstable inflow for these
    storms. However, the low-level mass response accompanying an
    approaching midlevel trough continues to favor a 40-50 kt low-level
    jet and ample low-level hodograph curvature (around 350-400 m2/s2
    0-1 km SRH per regional VWP). Given the well-established line of
    storms and this enhanced low-level helicity, a corridor of
    heightened tornado potential is evident across parts of southern LA
    into southwestern MS in the near term, and a strong tornado cannot
    be entirely ruled out.=20

    Thereafter, the squall line will continue eastward along a
    progressive cold front moving across southeastern LA, southern MS,
    and far southwestern AL -- where sufficient boundary-layer moisture
    and strong low/deep-layer shear will support a continued risk of
    damaging wind gusts and a couple tornadoes. A downstream tornado
    watch will be issued within an hour for this threat.
